vYacht NMEA Wifi Router
The vYacht's Wifi Router brings GPS and instrument data to your iPad and on board
computer. Simply attach the NMEA 0183 output of your charting plotter to the router
and the position is automatically broadcasted in a secure way via WiFi and ethernet.
All instrument data can be used in marine charting software like iNavX on the iPad or
most PC based navigation software.
The standard and cheaper iPad Wifi does not come with a GPS. If you still want to use it for
navigation the Wifi router is the perfect option. In addition to GPS it can even transfer AIS or
instrument data.
If you purchased the version with additional ethernet then you can even route internet through
the same wireless network.

Features
The new vYacht s WiFi Router comes as a kit: board and case. The main reason is to keep
the costs even lower for those who want the option.
Hardware
NMEA Interfaces Two isolated NMEA 0183 interfaces
WiFi / internet interfaces
WiFi for wireless network to iPad, PC and Mac
Two optional 10/100M ps-LAN/WAN-Port for ca le network
to PC and Mac and internet
Powersupply
12V DC (standard on- oard)
For fixed installations attach to navigational instrument
switch/fuse
Size(l x w x t 92.4 mm * 78 mm * 1.6 mm ( oard only)
Wireless range
Dependend on the location of the router. Installed centrally and
close to the nav corner the router works well everywhere on
sailing vessels measuring 40 feet. Please provide feed ack
a out experiences on much larger vessels.
Temperature range
Most components are rated -40 to +85 °C. However the
RT3050 chip on the actual wireless module is rated -10 to +55
°C operating temperature.
Power consumption
The FCC certified wireless module on this oard consumes the
vast amount of power. But even if used for heavy duty
downloads it will consume max. 1.5W.
Case
Available Colors lue, white or mixed ody/lock
Size(l x w x h 102 mm * 96 mm * 29 mm
Material
Printed PLA. PLA as a ase material is often used for through
hull fittings.
Printed PLA is very sta le and has good UV (ultra-violet)
tolerance.
Water resistance The router should e installed into a dry place. The WiFi only
version can e made watertight y using marine sealant.

Installation
The vYacht NMEA Wifi Router is not watertight. It should be installed into a dry location below
the deck.
1. Connect 12V on-board power supply to the vYacht NMEA Wifi Router s 12V input
2. Connect the NMEA 0183 output of your charting plotter, AIS or any other NMEA source
to either of the two isolated NMEA inputs of the router.
3. Depending on the NMEA source connected you will need to set the transfer speed to
usually 4800 Baud (standard) or 38.4k Baud (e.g. AIS). This setting is performed via
the WiFi Router Configuration (described below).
Usually no further steps are needed to serve NMEA data to your iPad or Android device via
WiFi.
In case you use a laptop or PC/Mac it is recommended to use the cable bound ethernet
connection rather than WiFi to safe power. Please refer to the Mac/PC set-up section.

iPad set up
The vYacht NMEA Wifi Router is configured as an automatic Access Point. This means that
usually no particular installation steps are necessary to retrieve NMEA data from it.
1. Connect iPad to the vYacht NMEA Wifi Router. Select the access point with the name
(SSID) vYachtWifi
2. Configure charting software to use vYachtWifi as the hostname (or the default IP
address 192.168.10.1) and 2947 as the port.

iPad and iNavX
As an example the configuration of iNavX on an iPad is shown. Instead of the router name
vYachtWifi the alternative IP address 192.168.1.1 was used to demonstrate that both
possibilities can be used.

PC or Mac set up
When using your PC or Mac in order to connect the the vYacht NMEA Wifi Router you have
two choices. Either you use the wireless access or you use the wired cable bound ethernet
connection.
Ethernet cable connection
1. Connect your PC/Mac s ethernet port with the router s ethernet port using the ethernet
cable coming as part of the vYacht NMEA Wifi Router package.
2. For Windows 7, please go to Start → Settings → Control Panel
Look for the section Internet and Network
Click on View network status and tasks → Manage network connection.
Right click Wireless Network Connection, and select Properties.
3. For Windows 7, double click Internet Protocol Version 4 (TCP/IPv4).
Select “Obtain an IP address automatically” and “Obtain DNS server address
automatically”.
Click OK to finish the settings.
Using the router for internet connections
Some boats have a 3G or other internet routers on board. The NMEA Wifi Router is
configured to allow the internet network traffic to be routed through the same vYachtWifi
connection.
Just make sure that the internet router has a different IP address from the vYacht NMEA Wifi
Router. The internet router needs to provide an IP address to the vYacht NMEA Wifi Router
via DHCP.
Connect the internet router to the blue ethernet jack of the vYacht NMEA Wifi Router.

vYacht NMEA Wifi Router Configuration
The vYacht NMEA Wifi Router provides a configuration tool which is installed on the router.
The configuration tool allows changes to the wireless IP address and the NMEA data port
number.
In order to access the configuration tool you need to connect to the Router as described
above. You can perform this configuration from either device with a web-browser (such as
Internet Explorer, Firefox or Safari).
The configuration can either be performed directly from your iPad after connecting to the
vYacht NMEA Wifi Router or from your PC/Mac.
Once connected open a web browser and type vYachtWifi into the browser s address field.
